TNPSC – WHITTAKER’S FIVE KINGDOM CLASSIFICATION

TNPSC – WHITTAKER’S FIVE KINGDOM CLASSIFICATION

 

  • H. Whittaker classified organisms based on
    1. Cell Structure
    2. Thallus Organisation
    3. Mode of Nutrition
    4. Reproduction
    5. Phylogenetic Relationship
  • Whittaker classified living organisms into
    1. Prokaryotic Organisms (KINGDOM = MONERA)
    2. Eukaryotic Organisms
  • Eukaryotic organisms can be further classified into
    1. Unicellular Organisms (KINGDOM = PROTISTA)
    2. Multicellular Organisms (KINGDOM = FUNGI, PLANTAE, ANIMALIA)
